Overview

When the float of the Changzhou metal tube float flowmeter moves upward with the change of flow rate in the measuring tube, and when buoyancy and gravity are balanced, the position of the float corresponds to a specific flow rate value. At this point, the circulation gap area between the float and the cone tube is fixed, which is proportional to the rising height of the float. The signal is transmitted to the indicator through magnetic coupling transmission to display the flow rate

Product Details

ChangzhouMetal tube float flowmeterIt is a variable area flow measurement instrument that reflects the flow rate by the displacement of the float in a conical tube, suitable for measuring gases, liquids, and vapors. ‌

whenThe float moves upward in the measuring tube with the change of flow rate. When buoyancy and gravity are balanced, the position of the float corresponds to a specific flow rate value. At this point, the circulation gap area between the float and the cone tube is fixed, which is proportional to the rising height of the float. The signal is transmitted to the indicator through magnetic coupling transmission to display the flow rate. ‌

Product Features:

1. All metal structure: corrosion-resistant, high-pressure resistant, suitable for high temperature environments. ‌
